LNT4061F No Picture & power indicator blinks 3 times

by krwade / April 14, 2009 1:03 PM PDT

Good evening, I have a LNT4061F that has just started havung problems. I can't turn it off unless i unplug it from the outlet, there is no picture with the exception of agreen line at the top and then through the middle. When I plug the unit back in the power indicator flashes 3 times pauses and begins flashing again. I have disconnected all inputs to no avail. I have seen some other threads that relate to this problem somewhat but not exactly. Any help or advice would be greatly appreciated.
Thank You

krwade,

My best suggestion is to get the unit serviced. It may be a power supply or board issue, but without looking at it, it's difficult to diagnose.

Thanks for the reply. I did leave the unit unplugged overnight and it came back on today. I am going to call for service tomorrow and hope for the best.
Thanks

Mine has the same problem and repair guy is coming in the morning .

Samsung should be fixing these tvs for free as no way the power boards going so many tvs is not a design problem .

started off as being slow to come on and then it started clicking for a while and then starting, then yesterday it crapped out. taking it for service this week. i have to say this TV was a major lemon. dead 5 months after the 1 year warranty expires is just sad. plus, i already had a new main board installed under warranty 2 months after I got it.

this many defects of the same type is certainly a design defect!

bad capacitors.......
by K1196A / June 2, 2009 1:37 AM PDT

I opened up the set last night and inspected the power board for bad capacitors (had read on the AVS forum that that may be the issue). Sure enough, there were 4 bad capacitors (clearly bulged). All 4 were 1000 microfarad, 10v, 105C. I took it to a local place that is going to replace the cheap Chinese capacitors for around $40. I'll be picking up the repaired board tonight and will post results tomorrow.

Worked great! Unit turned on instantly the first time I hit the switch. Total repair was $37.

This is at least something to look into for those who are out of warranty.

Same problem Cheaper Fix!!

Thanks for posting this when diagnosing your trouble. I had the same problem. On initial inspection of the power board, two capacitors were leaking and clearly budlged.

The ones that were defective for me were the 2200uF 10V caps. I replaced them with 2200uF 16V and also picked up some 1000uF incase those crap out on me.

With the spare parts the total fix was $5.65 (Including spare parts!).

If you are familiar with circuit boards and know how to solder this is an easy fix.

4hr job for a rusty electronic technician without the right tools!
